犯错不自知是一个老生常谈的问题，很多初学者在练习的时候并不会意识到自己其实处在一个很紧张的状态上，这里要多多录音录像，自己检查自己在弹奏时的一些细节，又或者可以请老师纠正。
Making mistakes without knowing it is a common saying. Many beginners will not realize that they are in a very tense state when they practice. Here, we should make more recordings and videos to check some details when playing, or ask the teacher to correct them.
通常我们会忽略的一些应该放松的地方有大臂和肩膀，这些地方的僵硬会导致背部、颈部的酸痛，尤其在速度练习时体现更加明显。要达到手臂在琴弦上左右移动自如，肩关节必须放松。
Usually we will ignore some places that should be relaxed, such as the big arms and shoulders. The stiffness of these places will lead to back and neck pain, especially in speed training. In order to make the arm move freely on the string, the shoulder joint must be relaxed.
二、慢练再慢练，精炼再精炼
2、 Practice slowly, refine again
当如何放松还未变成习惯性技巧之时，只有不断地练。在练习中慢慢地体会，倾听放松带来的优美音色，并且与紧张音色做对比，使放松的状态贯穿曲目始终。
When how to relax has not become a habitual skill, only practice constantly. In the practice, slowly experience, listen to the beautiful tone brought by relaxation, and compare it with the tense tone, so that the relaxed state runs through the whole track.
我们在演绎作品中会经常遇到较难的技巧，比如轮指、泛音、装饰音等等，这不是一朝一夕能完成的，需要多次重复慢练，或将某一重点、难点提出来单独练至放松自如、流畅连贯。
We often encounter more difficult skills in the interpretation of works, such as index wheel, overtone, decorative tone, etc., which can not be completed overnight. We need to repeat the slow practice many times, or put forward a certain key point and difficulty to practice alone until relaxed, fluent and coherent.
三、注意感情和呼吸
3、 Pay attention to feelings and breathing
在演奏过程中加我们可以适当去揣摩感觉，去呼吸，去感知筝曲内容，这样的话我们可以较快的进入全身放松的状态。平时的练习中，呼吸问题很关键，根据乐曲的节奏去呼吸，有节奏地呼吸，保证乐曲节奏稳定、声音平均、节奏准确。
In the process of playing, we can properly understand the feeling, to breathe, to feel the content of Zheng music, so that we can quickly enter the state of whole body relaxation. In the usual practice, breathing is very important. Breathe according to the rhythm of the music and breathe rhythmically to ensure that the rhythm of the music is stable, the sound is average and the rhythm is accurate.
